bhyveloader does work like this. And even if there is nobody to listen
to the loader, things to continue. It just takes 10 sec.

But once in a while I have trouble getting grub-bhyve to act the same.
If I connect it to a nmdm-device it just waits for me to connect.
And if I do not specify a device, it is nog possible to run it in the
background.

A inbetween sulution at the moment is to run grub-bhyve -c /dev/null.
That continues, dus does not offer the possibility to interfere in the
boot process. At least not for my ubuntu-12.04 VMs.

So a flag with grub-bhyve to not require a forground process, or even
better: ignore flowcontrol on the -c device, would be nice.
